I am looking for the best setup for a dual dss system. As a new user, I do not really know much about the different types of boxes available. What are the basic differences? Which are the best? I am planning to have the two boxes in the same room, so which support seperate IR codes to eliminate accidental channel switching. Also, since I will be using this setup (mostly to watch multiple football games on seperate tv's), do I really need to top of the line boxes.

Thanks for any information and suggestions.
